About the Rockbox Android port: http://www.rockbox.org/wiki/AndroidPort You can find on that page links to Rasher's daily builds from unmodified source. My experience has been that some work well and some don't, which is to be expected on an unstable port. The source from the last stable release, 3.10, produces a really nice stable, fully functional build.

I obtain source using git and I build on a Debian Stable x86 PC. My package is signed only with the debug key so you can't upgrade to or from someone else's Rockbox build; you need to uninstall RB and then install the RB you want. The signing offers no guarantee of the package's integrity, or of mine. I offer the package as a convenience as it costs me nothing to do so except a few minutes of my time.

I expect that this build will work on any Android device with a screen resolution 480x800 or larger but I only have the A43IT and that is the only device on which I know it works.

I don't intend to build a newer Meier patched android Rockbox package until the next stable Rockbox release. In the meantime Technical Support is available toll free at 0800-UR-MOM.
